JESSE PALMER, OF GLEVELAND, OHIO.`

IMPROVED KNIFE-POLISHER.

Specification forming part of Letters Patent No. 48,305, dated June 20,1865.

To all whom it may concern:

Beit known that I, JESSE PALMER,of Cleveland, in the county of Cuyahogaand State of Ohio, have invented a new and Improved Knife-Polisher; andI do hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,making a part of this specification, in which- Figure l is a perspectiveview'of my invention. Fig. 2 is a longitudinal section taken in avertical plane through the polisher. Fig. 3 is a vertical cross-sectionthrough the same.

Similar letters of reference indicate corresponding parts in the severalfigures.

The object of my invention is to construct a knife-polisher in suchmanner that the buffers, between which the knife is moved, will act withgreater force upon the point of the knife-blade, or that portion whichrequires the most rubbing to polish or clean it, and at the same timesaid buffers will conform to the longitudinal taper of the knife-blade,and act upon both sides thereof simultaneously, as will be hereinafterdescribed.

To enable others skilled in the art to understand my invention,l willdescribe its construction and operation.

In the accompanying drawings, A represents an oblong box or trough,consisting of a horizontal bottom provided with side ledges, a a, and ahinged eover, B. This cover is hinged at cto one end of the trough A insuch manner that when the free end ofthis cover is depressed thehingedend will slightly bind upon the upper surface of the bottom of thetrough at and near the hinge, as shown in Fig. 2. 4The upper surface ofthe trough A and the bottom surface of the hinged cover B are lined withcloth, leather, or other suitable substance, which will act as a bufferfor polishing the knife-blades, which are introduced one at a timebetween said surfaces, and polished by pressing upon the free end of thecover or upper buffer, and giving to the blades a longitudinal movement.While a knife is being polished it is conned between the two but'-ng-surfaces by the side strips or ledges, a a, which not only preventthe blade from slipping 'out of place, but also keep thepolishing-powder from escaping from the machine.

It will be seen that the hinged buii'er B will conform to thelongitudinal taperof the knives, so as to expose both surfaces thereof tothe actions of the buffers when this bueris pressed upon by the hand.

As the points of knives, particularly of ta ble-knives, most generallyrequire more rubbing to polish them than the rear portions, I have hungthe buffer B so that it will press hardest upon the points of theblades, and with some degree of force upon the rear portions thereof atthe same time.

The knob C, which is affixed at or near the free end of the buffer B, isused as a handle in the manipulation of this cover, and the pin D, whichprojects from the bottom of the trough A, is used as a means for aixingthe machine temporarily to tables or other stationary objects for thepurpose ot' keeping it steady during the operation of polishing knives.

I am aware that it is not new to employ two 'narrow hinged buffers forpolishing knives;

nor is it new to use two parallel bufting-surfaces for this purpose, andtherefore I do notv lay claim to these conirivances. The hinged buffersabove referred to operate only upon a small portion of the knifefhladesat a time, and do not conform to the longitudinal taper ofthe blades,nor act with greater force upon those portions which require the mostrubbing. The

.parallel buffers are not hinged together, and

consequentlydo not conform to the taper of the blades.

Having thus described my invention, Iclaim as a new and improved articleof manufacture- A knife-polisher constructed and operating as hereindescribed.

JESSE PALMER.
